Abstract

Compositions exhibiting water resistant anti-static properties prepared from a thermoplastic polymer and a polymeric anti-static salt is disclosed.

Description

The thermoplastic compounds, its manufacture method and the purposes that contain polymeric anti-static salt
The cross reference of related application
The application requires U.S. provisional application No.60/533, the right of priority in 173 (December 30 2003 applying date).
Technical field
The present invention relates to contain the thermoplastic compounds of polymeric anti-static salt, particularly contain the transparent composition of polymeric anti-static salt.
Background technology
Most polymers or blend polymer are non-conductive.Thereby, when processing and use polymkeric substance, produce static charge accumulation.Charged polymer in-mold product can attract the small-particle dust, and therefore hinders smooth surface appearance.Be attracted to the minimizing that particle on the molded article surface also may cause the goods transparency.In addition, static charge may seriously be disturbed the production technique of this base polymer.
Static inhibitor is a small molecule material, and it can add in the polymkeric substance to reduce the tendency that their produce static charge, and maybe when having electric charge, these static inhibitor promote the dissipation of this type of electric charge.The normally hydrophilic in essence or ionic of static inhibitor.In the time of on being present in surface of polymer material, they promote transfer transport, and therefore eliminate the accumulation of static charge.Static inhibitor is used with two kinds of methods.A kind of method is used outside static inhibitor, by being sprayed in the surface or the impregnated polymer material is used.Second method is used inner static inhibitor, and it joins in the polymkeric substance in first being processed.The static inhibitor of using by this way must be heat-staple and work in-process can be moved to the surface.
Because there are many static inhibitor to have the main component of surfactant additive as them, suitable a kind of can according to circumstances therefrom the selection.Surfactivity can comprise in the moulding process migration of agents to product surface and eliminate ability at the static charge accumulation of product surface.Yet, when as inner-during the static inhibitor used, the anion surface activity additive is difficult to use because they consistency and uniformly dispersed aspect relatively poor and tend to decomposition or deterioration during when heating.Contain quaternary nitrogen (quarternary nitrogen) in the cation surface activating additive molecule, on the other hand, although the antistatic property of amophoteric surface active additive is good, however they only under limited situation, can use because their thermotolerance extreme differences.As for nonionic surface-active additives, they are more compatible with polymer materials, die down but on antistatic property, be inclined to, and their effect disappearances under normal temperature or high temperature in time.In addition, because the limited thermostability of these non-ionic surface active static inhibitor, the use of they and engineering thermoplastic resin such as aromatic polycarbonate also is restricted, because this resinoid is processed during this temperature.Therefore, this class surfactant additive influences the optical property of aromatic polycarbonate unfriendly.
Although metal organic sulfonate is reported, especially static inhibitor is used in the inside of using as the polycarbonate and the vibrin of molding under the high temperature, and not only the consistency with resin is not enough for they, and their thermotolerance is also not enough simultaneously.The negative consequence that consistency is not enough is, because this type of static inhibitor, the transparency characteristic of some polymer materials incurs loss.Salt (organic sulfonic acid De Phosphonium, ammonium salt) also is known, and particularly the An of perfluorinated alkyl sulphonate is with phosphonium salt.
Although present known static inhibitor can be buied, make thermoplastic compounds have the static inhibitor of good resistance antistatic property but still need further to improve to provide, this antistatic property still keeps good along with the prolongation of time and/or after being exposed to water.Preferably, provide this type of improvement and do not damage the optical property (comprising transparency) of thermoplastics.
